product details
Industrial automation instrument control box according to different instrument configuration,environmental requirements and different shape design and internal control layout(including on the surface of the secondary instrument,the site of the primary instrument,etc.)constitute the control system.It is widely used in oil refining,metallurgy,chemical industry,light industry,textile,national defense,electric power,aviation,shipbuilding,medicine and machinery and other industrial production process control systems.
Industrial automation instrument control cabinet,is the company's years of mature experience in control,after repeated demonstration and various systems successfully debugging and running,carefully designed and successfully used for field parameter monitoring and DCS monitoring of the comprehensive electrical control cabinet.Mainly used for field parameter monitoring and alarm control of various equipment.
Industrial automation instrument control box main instruments and electrical components used at home and abroad famous electrical brands.Stable and reliable quality.According to different requirements and different application environments,corresponding detection and control items are equipped.In general,various types of local cabinets can monitor the working status of system equipment,and various signals can be visually displayed on site.Meanwhile,DCS connection port can be equipped to facilitate DCS configuration of large fan system,so as to realize dual control of local and central control.
Under normal circumstances,the JPK series fan on the instrument control cabinet control mode for the signals(including temperature,pressure,valve position,vibration,displacement,speed,etc.)via cable transmission to the in situ instrument cabinet,into the secondary instrument for display and signal processing,combining the scene control,control cabinets for various signal alarm again,start-stop and interlock,and the corresponding signal is converted into standard signals along with all kinds of alarm and running state far to DCS system,centralized monitoring shall be conducted by the DCS system.For local control of large equipment,PLC(programmable controller)can be used as the core,through different functional modules to complete data acquisition,operation,display and control,forming a PLC control system,and directly communicate with DCS.
According to the user's different circumstances,different occasions,different control requirements,on behalf of the user for system design,installation and debugging,to meet the requirements of different users.
